The present project departs from a study on the treatment of emergency situations, where it says that an infrastructure of communication, on this type of scenes, has to implement the interoperability and the control of access, between the different elements that take part on it, using the conversion of attributes. So to materialize this study there has been realized an analysis of the needs of the application and a detailed design of the modules that they form it. A tool of simulation for environments multi-domain has been implemented. Finally a set of tests have been realized to verify his reliability with regard to the original study.
